WINDOW CONSTRUCTION AND FASTENING AND HINGE.

SPECIFICATION forming part of Letters Patent No. 325,333, dated September 1, 1885.

Application filed May 6, 1885. (No model.)

To ctZZ whom/it may concern:

Be it known that I, OLE FLAGSTAD, a subject of the King of Norway, and residing in the town of Hamar, in the Kingdom of Norway, have invented certain new and useful Improvements in \Vindow Construction and Fastenings and Hinges; and I do hereby declare the following to be a full, clear, and can act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in windows, the object of the same being to provide improved devices for securing the sash in the frame,whereby the sash can be turned to enable both sides of the glass to be easily reached.

A further object is to provide devices for preventing water from settling and freezing between the frame and sash. A further ob ject is to provide an improved catch for looking the sash in a closed position.

\Vith these ends in View my invention consistsin the parts and combinations of parts, as will be more fully described,and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in front elevation of a window embodying my invention. Fig. 2 is a view in horizontal section of the same. Fig. 3 is a similar view, showing the window in an open position. Fig. 4 is a vertical sectional view of the same, showing, also, a modified arrangement of rollers. Fig. 5 shows the rollers detached, and Fig. 6 shows a detached view of the catch.

A represents a window-frame of any approved design, provided with upper and lower grooves, a, and with the side grooves or recesses, c and d, in which the opposite side edges of the sash B rest. The groove 0 and the corresponding end of the windowsash are shown as being semicircular in shape; but they can he changed to any other shape desired. The section or rail (1 of the sash B is provided at its upper and lower ends with pins c, the upper one of which carries a roller, 0, which latter rests within the upper groove of the frame, while the lower one rests within a socket, c of the truck 6 which latter runs in the bottom groove of the frame. The lower pin, e, is swiveled in the socket of the truck, which permits the sash to be swung outward or inward when desired.

D are rods the ends of each of which are bent in opposite directions at right angles to the main body of the rod, and respectively journaled in bearings f, secured to top and bottom of the window-frame, and in bearings f, secured to the top and bottom rails of the sash.

From the above construction it will be seen that if the end (I of the sash be pushed outwardly, the rods D cause the opposite end, (1, of said sash to move toward the center of the frame until it assumes the position shown in Fig. 3. The position of the sash when in an open position depends altogether on the length of the rods and their attachments to the sash and frame and the length of the grooves a.

The rods D are preferably provided with enlarged or capped upper ends, which prevent them from displacement, while their lower ends are without caps, for the purpose of permitting the window-sash to be removed from the frame whenever desired. When the lower ends of the rods are disconnected from their respective bearings, the window can be removed by first turning it to the position shown in Fig. 3 and tilting it sidewise until the upper pin, 6, leaves or falls below the groove, and then lifting the sash while in a tilted position until the lower roller or pin leaves the lower groove.

To prevent the sash from freezing fast by water trickling down between the inside of the sash and the frame, I insert or otherwise secure a metallic strip, F, to thewindow-frame in such a position as to form an abutment for the sash when the latter is in a closed position. In freezing weather the water, as it comes in contact with the cold metal, immediately freezes and prevents further penetration. The layer of ice already formed, on account of its thinness, cannot hinder the opening of the window, and in any event is in a position to be easily removed,if desired. If desired, the strip can be secured to the sash instead of the frame.

To lead off unfrozen water from the grooves a, I have provided the openings 9, which latter connect with the bottom of the groove in the lower portion of the frame.

For fastening the sash in position, a variety of devices can be used, and the choice of the same will depend on the construction of the window and whether the sash is to turn about a vertical (as shown in the drawings) or ahorizontal axis. For a window constructed as shown in the drawings, the catch shown in Fig. 6 is particularly applicable. This catch consists, essentially, of a plate, h, pivoted to a staple, h, secured to the sash, and provided at its inner end with perforated wings, through which the hook 7L2, secured to the frame, passes, and with a pivoted handle, If, for operating the spring h, which latter is rigidly secured at its lower end to the plate h, and bent at its upper end to engage the handle 11. The hook it", when the parts are in a locked position, rests between the spring and the handle, and is provided with a notch in which the spring This prevents the catch from becoming accidentally unlocked. By pushing on the upper end of the handle the spring is forced outward and disengaged from the notch, and then, by moving the whole device either up or down, the parts are disengaged or unlocked.

If desired, the handle If can be formed integral with the plate h, and the spring h, in-

stead of being bent toward the handle, can project upwardly, forming a thumb-piece, as shown in dotted lines, Fig. 6, and answer all necessary purposes. To operate this modified construction of catch, it is simply necessary to press the spring back with the thumb and move the handle, as before described.

Instead of grooving the windoW-frame,guide ways or tracks could be secured to the outside of the frame, and the rollers secured to bearings on the outside of the sash, as shown to the left hand of Fig. 4. This latter construction is particularly adapted to prevent freezing of the parts.

It is evident that numerous changes in the construction and relative arrangement of the several parts might be resorted to without departing from the spirit and scope of my invention; hence I would have it understood that I do not limit myself to the exact construction herein described, but consider myself at liberty to make such changes and altera tions as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with a window-frame, and a sash provided near one end with bearings, which latter engage grooves or tracks formed in or secured to the frame, of rods pivoted to the sash and frame, substantially as and for the purpose set forth.

2. The combination, with a window-frame and a window-sash, of rollers journaled to the sash near one end thereof, and engaging corresponding tracks or ways in the frame, and rods pivoted to the frame and sash, substan tially as shown.

3. The combination, with a grooved frame and a windowsash, of the rollers secured to the sash and engaging the grooves, and the bent rods connecting the frame and sash.

4. The combination, with a window-frame and a swinging sash, of a metal strip located between the sash and frame, substantially as and for the purpose set forth.

5. The combination, with a window-frame having 'upper and lower grooves, and the water-outlets g, and a window-sash having bearings, which latter rest within said grooves, of the rods pivoted to the sash and frame.

In testimony whereof I have signed this
